Answer: When you fire a gun from the perspective of newton's third law there is an equal and opposite reaction. This is what makes the bullet go forward and the gun kick back.
Explanation: when you fire a gun you pull the trigger, after you pull the trigger a mechanism in the gun goes forward very quickly to strike the primer on the bullet. The bullet will propel forward causing the gun to go backward into your shoulder.
Answer:
The mass of the another block is 60 kg.
Explanation:
Given that,
Mass of block M= 100 kg
Height = 1.0 m
Time = 0.90 s
Let the mass of the other block is m.
We need to calculate the acceleration of each block
Using equation of motion
Put the value into the formula
We need to calculate the mass of the other block
Using newton's second law
The net force of the block M
....(I)
The net force of the block m
Put the value of T from equation (I)
Put the value into the formula
Hence, The mass of the another block is 60 kg.
